A man walks through the wreckage left this morning after a nighttime Israeli strike on a storage depot in the town of Choueifat at the southern edge of Beirut, Lebanon. Israeli aircraft targeted Hezbollah's strongholds in south Beirut and attacked infrastructure in the Lebanese capital today, killing two people.

BEIRUT, Lebanon — Israeli warplanes pounded Hezbollah's south Beirut stronghold and roads around the country, killing at least 15 Lebanese as they fled the onslaught. Hezbollah expanded its rocket fire, hitting another of Israel's main cities, and Israel warned that the guerrillas could strike Tel Aviv.

A senior Israeli intelligence official said Iranian troops helped Hezbollah fire a missile that damaged an Israeli warship off the Lebanese coast Friday night.

The official, who spoke on condition of anonymity because of the sensitive nature of the information, said about 100 Iranian soldiers are in Lebanon and helped fire the Iranian-made, radar-guided C-102 at the ship that killed one and left three missing.

The Lebanese guerrilla force has shown an increasing sophistication since snatching two Israeli soldiers in a cross-border raid, sparking Israel's largest assault against Lebanon in 24 years.

Five Hezbollah rockets hit Tiberias in northern Israeli on Saturday, causing no injuries — the first rocket attack on Tiberias, about 22 miles south of the border, since the 1973 Mideast War. An Israeli intelligence official said Hezbollah has rockets with ranges of 60 to 120 miles that could reach Tel Aviv, Israel's largest metropolitan area.

At least 88 people have died in Lebanon, most of the them civilians, in the four-day Israeli offensive, sparked by Hezbollah's capture of two Israeli soldiers in a cross-border raid. On the Israeli side, at least 15 have been killed — four civilians and 11 soldiers.

In successive early morning raids that continued through the afternoon, Israeli warplanes pounded roads, destroying one bridge after another, splitting large parts of the country.

At least 12 Lebanese villagers, including women and children, were killed in what appeared to be an Israeli airstrike on a convoy of vehicles evacuation a village near the border with Israel in southern Lebanon, a witness said. The convoy was leaving the village of Marwaheen, which abuts the border, when it was attacked. Associated Press Photographer Nasser Nasser said he counted 12 bodies in two cars that burned from the attack shortly after midday.

At least three civilians were killed in another Israeli airstrike on the main highway linking Lebanon to Syria.

Israel also renewed bombardment of south Beirut suburbs, stronghold of Hezbollah which was blasted by several raids early and late Friday, destroying the headquarters of Hezbollah leader Sheik Hassan Nasrallah and his residence. Nasrallah survived unharmed, said Hezbollah TV.

Black smoke billowed from the Haret Hreik neighborhood after four loud impacts reverberated across the Lebanese capital. Witnesses said the planes were attacking Hezbollah's security compound in the area, a sealed-off bloc of buildings where Nasrallah has an office and residence, and where the Shura Council political decision-making body is located.

As the fighting continued unabated, Lebanon sought support from fellow Arabs whose foreign ministers were meeting at an emergency session in Cairo on Saturday to discuss the worst Israeli attack since the 1982 invasion of the country.

Lebanese Foreign Minister Fawzi Salloukh presented his fellow Arab League members with a draft resolution condemning Israel's military offensive and supporting Lebanon's "right to resist occupation by all legitimate means."

President Bush and Russian President Vladimir Putin also discussed the worsening situation, but the two appeared divided on how to restore calm.

Bush blamed Hezbollah and Syria for the escalating violence in the Middle East. "In my judgment, the best way to stop the violence is to understand why the violence occurred in the first place," Bush said. "And that's because Hezbollah has been launching rocket attacks out of Lebanon into Israel and because Hezbollah captured two Israeli soldiers."

Putin said it was unacceptable to try to reach political goals through abductions and strikes against an independent state. "In this context we consider Israel's concerns to be justified," he said. At the same time, he said, "the use of force should be balanced."

The attack on fleeing Marwaheen residents followed an Israeli warning by a loudspeaker from a facing Israeli military position across the border that residents of Marwaheen had to leave the village by evening. No reason was given for the Israeli ultimatum.

The convoy of several vehicles was hit near the border fence about half a mile from the village.
